BACKGROUND OF THE INVENTION

The proliferation of electronic and electrical devices is a key factorfueling an ever-increasing demand for additional alternating current(AC) outlets at home, on the road, and in the workplace. Often there aretoo many devices and not enough outlets. Additionally, devices includingcalculators, phones, and laptops use AC to direct current (DC) powerconverters (commonly called wall-bricks) to connect to AC power outlets.Due to their non-standard bulky form-factors, wall-bricks often take upmore than one outlet, exacerbating outlet-shortage problems and drivingusers to seek solutions.

A popular remedy is to use multi-outlet power strips. However, thesepower strips provide an ineffective solution because they fail toadequately address all of the problems created by, and associated with,the increasing prevalence and use of wall-bricks.

For example, a user who owns six devices buys a power strip. Whileconnecting the equipment, the user realizes that two devices usewall-bricks. Upon plugging the bricks into the power strip, the userdiscovers that only two or three of the six outlets remain open, leavingat least one outlet short. After spending $25-$200, the user expected tobe able to use all the outlets, but now must buy one or more additionalpower strips to plug-in the remaining devices.

Low-cost power strips provide additional outlets, but do not adequatelycondition or stabilize incoming power, increasing the risk of equipmentmalfunction or outright failure. Moderate to high priced surgeprotectors perform well, but bulky wall-bricks often cover multipleoutlets, reducing the number of devices that can be connected.

Additionally, wall-bricks often generate heat and electricalinterference in addition to passing along the ambient AC conducted sags,spikes, surges, and noise generated by the power-grid and carried alongAC power-lines throughout industrial, office, and residential settings.Electrical power disturbance events cause data loss and damageequipment. Wall-bricks pack and travel poorly, create cable-clutter, andare an eyesore.

Damaged equipment and downtime costs are a growing concern among users.As technology has advanced, business, commerce, home, and industrialusers have become increasingly dependant on the health of the networksthat supply and manipulate data and information. Additionally, thegrowing emphasis on network speed and the sheer volume of transactionsthat can take place in a fraction of a second make the prospect ofdowntime that much more ominous. The cost to business and industry ofhuman or naturally caused power surges and outages has becomesubstantially more detrimental.

It is clear from the statistical evidence that power conditioning is avital issue and one whose importance is only going to increase. Clean,constant, noise-free power is required to ensure the proper operation,and to protect the delicate circuitry, of today's electronic andelectrical devices.

Presently, systems and methods are needed that simultaneously solveoutlet-shortage and transient voltage surge and noise problems. Newsystems and methods are needed to eliminate wall-brick issues and otheridentified problems.

In oneembodiment, an automatic sensing power system (ASPS) component isembedded in an electronic device, such as a laptop computer, and a powerdelivery component resides in an ASPS, such as a power strip or areceptacle.

In one embodiment, upon connection to the ASPS, the laptop communicatesits power requirements to the ASPS via a power cord. The ASPS processesthe request and supplies the appropriate power. Inexpensive low voltageelectrical cords and modular adapters replace the wall-bricks typicallysupplied with cell and desk phones, personal digital assistants (PDAs),computers, mobile phones, digital cameras, cordless drills, faxmachines, and other electrical devices. The ASPS is programmable andupgradeable.

The ASPS solves many problems currently encountered by home, office, andindustrial consumers. The ASPS couples with single and multi-receptacleplug-in and hard-wired surge suppression devices, AC/DC power convertersand transformers, and a wide-range of electronic and electricalappliances, tools, and devices.

In one embodiment, the ASPS eliminates wall-bricks by placing modular DCreceptacles in a power system. The power system has AC and DCreceptacles in one unit, thereby eliminating the need for multiple powerstrips. The power system includes communication and networkinginterfaces and systems over which communications may be transmitted,such as through Bluetooth, Ethernet, Firewire, and/or a USB connection.In this embodiment, the ASPS includes expanded data line protection,such as for cable, DSL, Ethernet, and modem protection. In anotherembodiment, the ASPS integrates gateway, network, and routercapabilities. Another embodiment incorporates data communication over abroadband connection. In one example, electronic devices communicatewith and through the power system via a DC connector or an AC connector.

In another embodiment, the ASPS includes a line-cord device with adetachable wall plug device. Once detached, the wall-plug device can bemoved between rooms or offices or taken on the road to replacewall-bricks.

FIG. 5 depicts an exemplary embodiment of an automatic power system(APS). The APS 502 of FIG. 5 includes an automatic sensing power system(ASPS) 102B, an electrical supply 504, an electrical device 506, and acomputing device 508. The ASPS 102B is used to automatically determinethe power requirements of the electrical device 506, including voltageand/or amperage requirements, and supply the appropriate power to theelectrical device.

In this embodiment, the electrical device 506 does not have a powerconverter. Instead, the electrical device 506 includes a simpleelectrical connector between the ASPS 102B and the electrical device.The electrical connector is not a bulky power converter, such as a wallbrick. The connector may be a standard power conducting wire, such asthose used for a laptop computer, a PDA, a mobile telephone, or anotherelectrical device (without the power converter).

The ASPS 102B receives power from the electrical supply 504. Upondetermining the power requirements, the ASPS 102B supplies the correctpower to the electrical device 506.

The ASPS 102B communicates with the computing device 508. The computingdevice 508 may be a computing device, data device, or another deviceconfigured to communicate with the ASPS 102B.

In one embodiment, the computing device 508 receives status data fromthe ASPS 102B, including faults, breakdowns in processes, if any, surgeidentifications, and other status information. In another embodiment,the ASPS 102B receives data from the computing device 508. In oneexample, the ASPS 102B receives control data, such as configurationdata, from the computing device 508.

In one example, a user uses the computing device 508 to load the powerrequirements of the electrical device 506 to the ASPS 102B. The ASPS102B stores the power requirements and uses the power requirements toprovide the appropriate power levels, including voltage and/or amperagelevels, to the electrical device 506.

In another example, the ASPS 102B receives data from the computingdevice 508. The computing device 508 is configured to transmit powerrequirements for the electrical device 506 to the ASPS 102B. In thisexample, the ASPS 102B is configured to assign a particular receptacle,such as a particular DC or a particular AC receptacle, to the electricaldevice 506. In this example, a user may plug the electrical device 506into a particular receptacle in the ASPS 102B, and the powerrequirements will be transmitted to the electrical device 506.

In one example, the computing device 508 is configured to enable theparticular receptacle for the electrical device 506. In this example,the computing device 508 also is configured to disable one or more otherreceptacles, including one or more other AC receptacles and/or DCreceptacles. In this example, disabling one or more receptacles providesa safety feature so that the electrical device 506 is not inadvertentlyplugged into a receptacle with the wrong power requirements, which mayresult in damaging the electrical device. In this example, an indicatorlight may indicate whether the receptacle is enabled or disabled toreceive power and/or to transmit power to an electrical device.

The ASPS 102B may receive configuration data and/or control data toconfigure one or more receptacles. For example, the ASPS 102B mayconfigure a first receptacle for a mobile telephone and a secondreceptacle for a computer. In this example, the first receptacle wouldprovide the correct power requirements to the mobile telephone, and thesecond receptacle would provide the correct power requirements to thecomputer.

In the above example, the electrical device 506 does not require an ASprocessing system, as described more completely below. This embodimentprovides flexibility to the user for devices not having the ASprocessing system.

It will be appreciated that the configuration data and/or control datamay be provided to the ASPS 102B in a variety of ways. In oneembodiment, the ASPS 102B receives configuration data identifying amodel of a particular electrical device 506, such as a device nameand/or a model name or number or another identifier. In this example,data identifying particular electrical devices and their powerrequirements reside on the ASPS 102B. In this example, the ASPS 102Bperforms a search, look up, or other process to identify the particularelectronic device model and its power requirements from the data storedon the ASPS. The ASPS 102B then can provide the correct power to theelectrical device 506.

In another embodiment, the ASPS 102B is configured to receive theparticular power requirements, including voltage and/or amperagerequirements, directly from the computing device 508. In this example,the ASPS 102B is not required to perform a search, look up, or otherprocessing operation to identify a particular electrical device's powerrequirements. In this example, after receiving the configurationinformation, the ASPS 102B configures a particular receptacle for thepower requirements.

FIG. 6 depicts another exemplary embodiment of an APS 502A. In thisembodiment, the electrical device 506A includes an AS processing system.In the embodiment of FIG. 6, power is transmitted from the ASPS 102C tothe electrical device 506A. Additionally, data is communicated betweenthe ASPS 102C and the electrical device 506A.

It will be appreciated that the power and the data may be transmittedover the same physical connection, one physical connection for the powerand another physical connection for the data, or multiple physicalconnections for the power and/or data.

In one embodiment of FIG. 6, the ASPS 102C identifies that an electricaldevice 506A has been plugged into one of the receptacles. Thisidentification may be made through hardware, software, firmware, orother methods. In one example, the electrical device 506A makes acircuit when the electrical device is plugged into the receptacle. Inanother example, the electrical device 506A causes the receptacle totransmit a signal when the electrical device is plugged into thereceptacle.

In one example, the electrical device 506A generates a power requestupon being connected to the receptacle. In one example, the requestincludes an identification of the particular electrical device. Inanother example, the request includes specific power requirements forthe electrical device 506A.

The ASPS 102C receives the request and determines the power requirementsfor the electrical device 506A. In one example, the ASPS 102C identifiesthe particular electrical device 506A and searches its data, such asthrough a look up, a search, or other determination, to identify thepower requirements for the electrical device 506A. The ASPS 102Cprovides the appropriate power, including the appropriate voltage andamperage, to the electrical device 506A.

In another example, the ASPS 102C receives a request for power from theelectrical device 506A. In this example, the request includes thespecific power requirements. In this example, the ASPS 102C is notrequired to perform a look up, search, or other determination toidentify the power requirements for the electrical device 506A. The ASPS102C provides the power to the electrical device 506A according to thepower requirements.

FIG. 7 depicts an exemplary embodiment of one or more processesoccurring in the ASPS 102D, the electrical device 506B, and theelectrical device 506C. The ASPS 102D communicates with a computingdevice 508B, and the ASPS 102D receives power from the electrical supply504.

Other examples exist. The communication system 1028is optional in some embodiments.

The DC receptacles 1030 are configured to transmit power from the ASPS102G to one or more electrical devices connected to the DC receptacles.The DC receptacles 1030 include one or more DC receptacles. In oneembodiment, a single DC receptacle is included in the ASPS 102G. Inanother embodiment, N DC receptacles are included in the ASPS 102G,where N is a number greater than or equal to one.

In one embodiment, one or more of the DC receptacles 1030 are barrelconnectors. The barrel connector includes a ground pin and power pin.The DC receptacle in this embodiment is a female barrel connector and isconfigured to receive a male barrel connector.

In one embodiment, the barrel connector also includes a switch and/orswitch detector configured to indicate when a mating barrel connector isconnected to the barrel connector of the DC receptacle 1030. Theprocessor 1002 receives a signal from the switch detector when a matingbarrel connector is connected to the connector of the DC receptacle.

In one example, the switch detector has a switch lead that is connectedto a ground lead when no device is plugged into the barrel connector.The switch lead also is connected to the processor 1002, and a switchdetector signal is transmitted via the switch lead to the processor.When the switch lead is connected to ground, the processor 1002 readsthe switch detector signal as a logic 0, which corresponds to ground.When an electrical device is connected to the barrel connector, theswitch lead is disconnected from the ground lead. The processor 1002reads the switch detector signal as a logic 1, which indicates anelectrical device is connected into the barrel connector of the DCreceptacle.

In one embodiment, an optional switch (not shown) is included betweenthe DC to DC regulator 1018 and the DC receptacles 1030. The optionalswitch enables a user to turn a selected one or more of the DCreceptacles 1030 on or off. In one example, each optional switchincludes one of the indicators 1024.

The communication interface 1032 interfaces to one or more types ofcommunication systems. In one embodiment, the communication interface1032 is a USB interface. In another example, the communication interfaceis an RJ-11 or RJ-14 telephone jack interface. In another example, thecommunication interface is an RJ-45 connector. In another example, thecommunication interface 1032 is an Ethernet-based interface. One or moreof the previously referenced communication interfaces and/or one or moreother interfaces may exist in a single embodiment. Other examples exist.The communication interface 1032 is optional in some embodiments.

The processor 1002 controls the operations of the ASPS 102G. Theprocessor 1002 controls the on and off states of the AC receptacles 1014by enabling and disabling the optical relay 1010 to connect anddisconnect the AC input power for output to one or more AC receptacles.The processor 1002 transmits one or more signals to the optical relay1010 to make or break a connection for one or more of the AC receptacles1014.

The processor 1002 controls the on and off states of the DC receptacles1030. The processor 1002 controls which DC receptacles 1030 will beenabled with DC power. The processor 1002 determines the DC power levelthat will be output from the DC to DC regulator 1018 for each DCreceptacle. The processor 1002 transmits a signal to the DC to DCregulator 1018 identifying the DC power level to be output to each DCreceptacle and enables the DC power output level for that DC receptacle.

The processor 1002 controls the transmission and reception of data toand from the modulator 1020. The processor 1002 receives data from themodulator 1020 and processes the data. The data may include, forexample, a specific or approximate DC voltage level required by anelectrical device connected to one of the DC receptacles 1030 and/or anidentification of the electrical device.

The processor 1002 determines the type of communication that will bemade via the modulator 1020. In one example, the processor 1002 controlsthe modulation of the modulator 1020 so that communications are made ina format receivable by the electrical device connected to the DCreceptacle 1030. The processor 1002 also controls demodulation of themodulator 1020 so that communications received from an electrical deviceare transmitted in a format receivable by the modulator 1020 andprocessable by the processor 1002.

The processor 1002 controls the indicators 1024. The processor 1002transmits one or more signals to one or more of the indicators 1024 foran indicator status. In one embodiment, the indicators 1024 are LEDs,and the processor 1002 enables a particular input to cause the LED toturn on. In another example, the processor 1002 enables another input ofthe LED to cause the LED to light a second color.

The processor 1002 controls start-up of the ASPS 102G. In addition, uponreceiving a reset signal from the reset controller 1026, the processor1002 retrieves the start-up programming from memory 1022 and resets theASPS 102G.

The processor 1002 processes communications received via the modulator1020 and the communication system 1028. The processor 1002 alsotransmits communications via the modulator 1020 and the communicationsystem 1028.

In one embodiment, the processor 1002 generates a user interface via thecommunication system 1028 for display, such as for display on a computersystem with a monitor. In this embodiment, the processor 1002 transmitsdata to the computer system for display. The data may include, forexample, voltage levels required for a particular DC receptacle 1030,instructions to enable a particular DC receptacle for a particularlevel, instructions to enable or disable one or more AC receptacles 1014and/or DC receptacles 1030, or other data.

In another embodiment, the user interface resides on a computer systemthat is communicating with the processor 1002 via the communicationsystem 1028 and the communication interface 1032. In this embodiment,the processor 1002 transmits data to the computer system for display bythe user interface. The computer system transmits data received from theuser interface to the processor 1002 for processing. In this example,the data may include, for example, voltage levels required for aparticular DC receptacle 1030, instructions to enable a particular DCreceptacle for a particular level, instructions to enable or disable oneor more AC receptacles 1014 and/or DC receptacles 1030, or other data.

In one embodiment, the processor 1002 monitors the output from the DC toDC regulator 1018 to identify the actual or approximate actual voltagebeing generated from the DC to DC regulator to a selected DC receptacle1030. The raw analog voltage level generated by the DC to DC regulator1018 is used as a feedback signal and is input back to the processor1002. This feedback signal is indicated by the dashed-line between theprocessor 1002 and the DC to DC regulator 1018 in FIG. 10. In thisembodiment, the processor 1002 has a voltage divider that divides thefeedback signal to a lower DC voltage range, such as between 0 volts and5 volts, samples the divided feedback signal with an analog-to-digitalconverter, and uses the sampled feedback signal to determine if anyadjustments must be made to the output of the DC to DC regulator 1018 tomaintain the proper output DC voltage. In one example, the voltagedivider is a circuit having two resistors.

In one embodiment, the processor 1002 transmits an adjustment signal tothe DC to DC regulator 1018 to adjust its output of a DC voltage for aparticular DC receptacle 1030. In one example, the adjustment signal isan analog output signal that is used to inject an offset into the DC toDC regulator 1018. In this example, the degree of offset is linearlyrelated to the output DC voltage of the DC to DC regulator 1018. Thisvoltage may be expressed as Voutput=Vadjustment*Beta, withBeta=GainFactor+Tolerance. The GainFactor is a gain specific to the DCto DC regulator 1018, and its value depends upon the exact design of theDC to DC regulator. The Tolerance is a parameter used to express theproduction tolerance of each DC to DC regulator. Ideally, the Toleranceis 0.

The feedback loop signal enables the processor 1002 to vary Vadjustmentuntil Voutput is equal to the DC voltage required by the electricaldevice connected to the particular DC receptacle. In other embodiments,the adjustment signal includes a raw digital format, rather than ananalog format. Other examples exist.

In one embodiment, when an electrical device is connected to one of theDC receptacles 1030, the processor 1002 causes a minimal level of DCpower to output from the DC to DC regulator 1018 to the DC receptacle.The minimal power level is enough DC power to initiate operations of theelectrical device, such as operation of the electrical device'sprocessor, but not enough DC power to fully power the electrical device.The minimal power level is low enough that it will not exceed powerlevels that may damage the electrical device. In this example, theminimal power level enables the processor of the electrical device tocommunicate with the processor 1002 of the ASPS 102G. The processor ofthe electrical device then is able to transmit the voltage requirementsor the electrical device's identification to the processor 1002 of theASPS 102G. The processor 1002 then configures the DC voltage level to beoutput from the DC to DC regulator 1018 to the DC receptacle 1030 inwhich the electrical device is connected and enables output of the DCpower to that DC receptacle.

FIG. 11 depicts another exemplary embodiment of a ASPS 102H. In theembodiment of FIG. 11, the ASPS 102H includes DC receptacle 1 1030Athrough DC receptacle N 1030B. Each DC receptacle 1030A-1030B has anassociated detector 1102-1104, such as a detector switch for the barrelconnector described above. Other examples exist. Each detector 1102-1104is configured to enable a signal to the processor 1002A identifying thatan electrical device connector has been connected to the receptacle1030A-1030B.

A modulator 1020A-1020B is configured to communicate between arespective DC receptacle 1030A-1030B and the processor 1002A. Theprocessor 1002A transmits communications to the DC receptacles1030A-1030B via the modulator 1020A-1020B and receives communicationsfrom the DC receptacles via the modulators.

A low current driver 1106 and 1108 and a high current switch 1110 and1112 are associated with each DC receptacle 1030A-1030B. The low currentdrivers 1106 and 1108 receive DC power from the DC to DC regulator1018A-1018B at a low current level and/or a low voltage level. The lowcurrent drivers 1106-1108 provide the DC power to the DC receptacles1030A-1030B. The low current driver 1106-1108 is used to signal to theelectrical device connected to the DC receptacle 1030A-1030B that theprocessor 1002A will transmit communications to, or receivecommunications from, the electrical device. In one embodiment, a lowcurrent driver 1106-1108 includes one or more resistors.

The high current switches 1110-1112 receive DC power from the DC to DCregulator 1018A-1018B at a high current level and/or a high voltagelevel. The high current switches 1110-1112 provide the DC power to theDC receptacles 1030A-1030B. The DC power provided by the high currentswitch 1110-1112 to the DC receptacle 1030A-1030B is used to charge orotherwise power the electrical device connected to the DC receptacle. Inone embodiment, a high current switch 1110-1112 includes a transistor ormultiple transistors configured to receive DC power from the DC to DCregulator 1018A-1018B and to receive an enable signal from the processor1002A. Upon receiving the enable signal from the processor 1002A, thehigh current switch 1110-1112 transmits the DC power to the DCreceptacle 1030A-1030B.

In the embodiment of FIG. 11, the processor 1002A and the modulators1020A-1020B are configured to communicate using voltage modulation. Inone embodiment, the modulator 1020A-1020B transmits communications to,and receives communications from, the DC receptacle 1030A-1030B using ahexadecimal format. In one example, one or more communications transmitASCII-based characters using hexadecimal format.

In one embodiment, the ASPS 102H of FIG. 11 operates as follows. The DCreceptacle 1030A includes a female barrel connector having a ground pin,a power pin, and a switch pin. The detector 1102 is the switch pin andswitching mechanism in this example.

When a mating jack is not connected to the DC receptacle 1030A, theswitching mechanism causes the switch pin to be connected to the groundlead. The switch pin also is connected to an input of the processor1002A. When the switch pin is connected to ground, the processor readsthe switch pin signal as a logic 0, which corresponds to ground.

An electrical device having a male connector is plugged into the DCfemale barrel connector receptacle. When the device is connected, theswitch lead of the detector 1102 is disconnected from the ground lead.In this example, pull-up resistors are connected to the switch leadbetween the detector 1102 and the processor 1002A. When the switch leadis disconnected from ground, the detector signal transitions to a logic1.

When the detector signal transitions to a logic 1, the processor 1002Adetermines that an electrical device is connected to the DC receptacle1030A. The processor 1002A causes a low current and/or a low voltagedriver signal to be generated from the DC to DC regulator 1018A throughthe low current driver 1106 to the DC receptacle 1030A. In this example,the low current signal is 24 volts DC and less than 5 milli-amps. Thelow current signal is enough power to turn on a processor for theelectrical device. However, the low current signal likely does not havesufficient amperage to damage the electrical device.

The low current driver signal is an indication to the electrical devicethat one or more communications will be transmitted from the ASPS 102Hto the electrical device. The processor 1002A transmits a query to theelectrical device through the modulator 1020A and to the DC receptacle1030A. In this example, the modulator 1020A uses voltage modulation totransmit the communication.

After the low current driver signal has been transmitted to theelectrical device, the processor 1002A causes the modulator 1020A totransmit the communication to the electrical device through the DCreceptacle 1030A. In this example, the processor 1002A transmits aseries of enable and disable signals to the modulator 1020A. In responseto the enable signals, the modulator 1020A outputs a voltage having anamplitude greater than a minimal amperage, such as 3 volts DC. Theelectrical device receives the voltage having the amplitude andrecognizes it as a logic 1. When the modulator 1020A receives a disablesignal, the modulator either outputs a voltage having a level below theminimal level or does not output any voltage at all. The electricaldevice identifies that the voltage is either below the minimal level orthat no voltage is received at all and reads this as a logic 0. Usingthis method, a series of 1s and 0s are transmitted between the modulatorand the electrical device as one more data packets.

The electrical device transmits a communication to the modulator 1020Athrough the DC receptacle 1030A, and the modulator transmits thecommunication to the processor 1002A. In this example, the processor1002A has a divider circuit that divides the voltage of thecommunication to a lower voltage, such as voltage between 0 and 5 voltsDC. The processor 1002A also has an analog-to-digital converter thatsamples the divided communication. The processor 1002A reads theconverted signal and identifies the communication type and the data inthe communication.

In this example, the communication from the electrical device is anacknowledgment indicating a status OK command. The processor 1002Atransmits a message via the modulator 1020A requesting a voltage codeand an identification string from the electrical device. The processor1002A receives a communication from the electrical device via themodulator 1020A with the voltage code and the identification string forthe electrical device.

The processor 1002A transmits a signal to the DC to DC regulator 1018Afor the requested voltage and enables the output from the DC to DCregulator to the high current switch 1110. The processor 1002A alsoenables the switch for the high current switch 1110 which causes the DCpower to flow from the DC to DC regulator 1018A through the high currentswitch 1110 and to the DC receptacle 1030A.

If the processor 1002A communicates with the electrical device while orafter the electrical device receives the DC power generated from the DCto DC regulator 1018A through the high current switch 1110, theprocessor 1002A disables the output from the DC to DC regulator to thehigh current switch 1110. The processor 1002A may accomplish this bydisabling the output from the DC to DC regulator 1018A, disabling thehigh current switch 1110, or both.

The processor 1002A then enables a low current and/or low voltage driversignal from the DC to DC regulator 1018A to the low current driver 1106.The low current driver 1106 transmits the low current driver signal tothe electrical device through the DC receptacle 1030A. The low currentdriver signal is a signal to the electrical device that a communicationwill be transmitted from the processor 1002A. In this example, theprocessor 1002A and the electrical device operate in a master-slaverelationship. In other embodiments, a polling relationship may occurbetween the processor 1002A and the electrical device. Other examplesexist.

After the low current driver signal has been transmitted to theelectrical device, the processor 1002A causes the modulator 1020A totransmit the communication to the electrical device through the DCreceptacle 1030A. In this example, the processor 1002A transmits aseries of enable and disable signals to the modulator 1020A. In responseto the enable signals, the modulator 1020A outputs a voltage having anamplitude greater than a minimal amperage, such as 3 volts DC. Theelectrical device receives the voltage having the amplitude andrecognizes it as a logic 1. When the modulator 1020A receives a disablesignal, the modulator either outputs a voltage having a level below theminimal level or does not output any voltage at all. The electricaldevice identifies that the voltage is either below the minimal level orthat no voltage is received at all and reads this as a logic 0. Usingthis method, a series of 1s and 0s are transmitted between the modulatorand the electrical device as one or more data packets.

Similarly, in this example, the electrical device transmits one or moredata packets to the modulator 1020A having a voltage amplitude thatindicates a logic 1 or a logic 0. The voltage levels are transmittedfrom the modulator to the divider circuit and the analog-to-digitalconverter on the processor 1002A and read by the processor as a logical0 or a logical 1.

FIGS. 23-43 depict an exemplary embodiment of a user interface (UI)2302. The UI enables a user to determine if an electrical device isconnected to the ASPS. In the embodiment of FIGS. 23-43, an electricaldevice is referred to as an automatic sensing-direct current andautomatic synchronous-data communication (asDC) device, and the ASPS isreferred to as an intelligent power hub.

The UI enables a user to select the voltage to be transmitted from theASPS to an electrical device and to select the DC receptacle to which itwill be generated. The UI also enables a user to turn one or more ACreceptacles and/or DC receptacles on or off. For exemplary purposes, theUI of FIGS. 23-43 is directed to only one AC receptacle (identified asan AC port on the UI) and only one DC receptacle (identified as a DCport on the UI). However, other UIs may enable selection of multiple ACreceptacles and multiple DC receptacles.

Additionally, a computer is connected to the power hub through a USBconnection in the embodiments of FIGS. 23-43. The UI in this embodimentis generated through the host computer and displayable on the computer'sdisplay.

When the computer is not connected to the power hub, the UI indicatesthat no power hub is connected to the computer and no asDC device isconnected to the power hub, as depicted in FIG. 23. When the power hubis connected to the computer, the UI indicates that the power hub isconnected to the computer via the USB port, as depicted in FIG. 24.

As depicted in FIG. 25, when an asDC device is connected to the powerhub, a window is displayed with the status change. The user selects the“OK” button on the status change window, and the status change windowdisappears. In other embodiments, the status window briefly appears andautomatically disappears after a selected period of time. The asDCdevice status indicates that an asDC device was identified, as depictedin FIG. 26. The asDC device identification is specified by values in twofields, including a name or identity field and an operating voltagefield. In the example of FIG. 26, the name or identity field may containa string of up to forty characters. In this example, the device isidentified as an “asDC Motorola 730” having an operating voltage of 5.29volts DC. Other examples exist.

When the asDC device is disconnected from the power hub, a status changewindow is generated, as depicted in FIG. 27. The device status indicatesthat no asDC device is connected to the power hub, as indicated in FIG.28.

An electrical device that is not configured to communicate with thepower hub is referred to as a non-asDC device. If a non-asDC device isconnected to the power hub, a status change window indicates that thenon-asDC device is connected to the power hub, as indicated in FIG. 29.The status change window suggests that the user manually enable a DCreceptacle.

The user may select a voltage to be output to a selected DC receptacle,as depicted in FIG. 30. In this example, the user selected the voltagelevel to be output to the selected DC receptacle. The user then selectedthe “force asDC port ON” to set the DC receptacle to the selectedvoltage level.

The user may elect to turn the AC receptacle on or off, as depicted inFIG. 31. If the user selects the check box for “AC port on/off,” theuser may turn the receptacle on and off. When the AC receptacle isturned on, the power hub status window indicates that the AC port wasenabled.

If the user again selects the check box for the AC port on/off, the ACpower for the AC receptacle is turned off. The check mark from the checkbox disappears, and a new line is entered for the power hub statusindicating that the AC port is disabled, as depicted in FIG. 32.

As depicted in FIGS. 33-34, the user turns the power on for the DCreceptacle. In this example, the user selects a different voltage to beoutput to the DC receptacle. The user then selects the “force asDC portON” check box. A check mark appears in the check box to indicate thatthe power is being transmitted to the DC receptacle. In addition, a lineappears in the power hub status indicating that the DC port was forcedon, as depicted in FIG. 34. In this example, the status line alsoindicates the code for the voltage and/or the device name.

The user may select the check box for the DC port again to force the DCreceptacle off, as indicated in FIG. 35. A status line is generated tothe power hub status indicating that the DC port was forced off.

The UI enables the user to update the firmware on the power hub, asindicated by FIG. 36. The UI enables the user to select from an openfirmware option and a download firmware option. The open firmware optionmay be used to locate a file that is to be installed, as indicated inFIG. 37. The user selects the file to be opened, and the contents of thefile are checked for integrity. If the integrity check is successful, anintegrity check window appears and identifies the firmware as beingvalid, as indicated in FIG. 38. When the user selects the “OK” buttonfrom the integrity check status window, the firmware is opened anddownloaded.

If the user selects the download firmware option from the display ofFIG. 36, a status change window is generated indicating that thefirmware download is starting, as depicted in FIG. 39. If the downloadprocess is successful, a status change window is generated indicatingthat the download is complete, as depicted in FIG. 40.

When the firmware has been downloaded, the user may select the reset onthe power hub or cycle the power supply for the power hub bydisconnecting the power supply from the power hub and reconnecting it.The user may relaunch the UI if desired.

A third option from the advanced menu option from FIG. 36 enables a userto change a target configuration of an asDC enabled device. When theuser selects the change target configuration option from the menu, anupdate target properties window is generated for display, as depicted inFIG. 41. The user enters new values for the asDC device name and itsoperating voltage, as depicted in FIG. 42. When the asDC device isconnected to the power hub, the power hub recognizes the device and itsrequired operating voltage, as depicted in FIG. 43.
